area chart temperature
This area chart displays average temperature over time, with the x-axis representing years and the y-axis showing temperature in degrees Celsius. Built with D3.js v6, the visualization uses d3.area() to generate the filled path, d3.scaleTime() and d3.scaleLinear() for coordinate mapping, and d3.axisBottom()/d3.axisLeft() for axes. Data is loaded asynchronously via d3.csv() from a remote Gist and rendered as SVG elements with a steelblue fill.
